Belltech Torsion Bar Keys make lowering or leveling your torsion bar equipped IFS truck or SUV simple, safe and cost effective. After broaching the high strength ductile iron casting to the appropriate degree that allows retention of the factory spring rate and ride quality, each key is then E-coated for a long durable corrosion free life. Whether using lowering or leveling keys, height adjustment ranges typically allow from 1 to 3" of adjustment.

Suspension components are key to making sure your car is riding smoothly on or off the road. With upgraded suspension components, you can unlock the full potential of your vehicles performance.

Since 1983 small company in Fresno, California had an idea to build the best performing lowering suspensions for the Chevrolet pickup. Fresno had been a haven for lowered vehicles and trucks were in abundance. Trucks were being lowered but their suspensions were terrible and not very roadworthy. Springs were either replaced with new ones not necessarily meant for the application and even worse they may be cut or heated with a torch at the local muffler shop to give the lowered stance that was cool. The stance looked good but the ride was terrible.
